Smoked Salmon During Pregnancy: Lox, Canned, and Cooked Options
Only cooked or shelf-stable: CDC lists refrigerated smoked salmon and lox as riskier in pregnancy. How to cook it, lox bagels, and what if you ate some.

The short answer: CDC lists refrigerated smoked seafood as a riskier choice during pregnancy, unless it is in a cooked dish. This includes refrigerated smoked salmon sold as lox or nova-style fish. CDC lists smoked fish in a sealed, shelf-stable package that does not need refrigeration before opening as a safer choice. Check the actual product and how you plan to serve it.
Is lox on a bagel different from cooked salmon?
Yes. Lox and other refrigerated smoked fish are generally served cold, without a final cooking step. FDA's pregnancy food-safety guidance advises avoiding refrigerated smoked seafood unless it is in a cooked dish, such as a casserole. A toasted bagel does not cook the fish placed on top of it.
For a cooked fish meal, CDC lists fish cooked to 145°F, or until the flesh is opaque and separates easily with a fork, as a safer choice. If using refrigerated smoked fish in a dish, cook the dish thoroughly rather than adding the fish after cooking.
What should I check on the package?
- Does it require refrigeration before opening? Refrigerated smoked fish falls under CDC's riskier category when eaten without cooking. “Smoked,” “lox,” “nova-style,” and “kippered” can appear on these packages; the word “smoked” alone does not establish shelf stability.
- Is it sealed and shelf-stable before opening? CDC lists this as a safer smoked-fish option. Follow the package's storage directions after opening.
- Which fish is it? Food-safety preparation and mercury are separate checks. Use the FDA/EPA fish chart to identify the species and serving guidance.
PregNut's smoked whitefish nutrient entry reports nutrients for a reference food; it cannot tell whether a product is refrigerated, shelf-stable, or heated. Our lower-mercury fish guide explains fish choices and weekly servings separately from this smoked-seafood handling question.
How do you cook smoked salmon when pregnant?
Cook it in the dish. CDC's Listeria prevention page lists smoked fish cooked in a casserole or other cooked dishes as a safer choice, and FDA's example is a casserole. Mix refrigerated smoked salmon into a baked pasta, potato bake, frittata, or quiche before it goes in the oven, and cook the dish through. Smoked salmon laid on top of a hot dish as a garnish has not been cooked.
Common questions
Can I eat smoked salmon in the first trimester?
CDC's chart does not change by trimester. Refrigerated smoked salmon is on its riskier list throughout pregnancy unless it is in a cooked dish.
What if I ate smoked salmon or lox while pregnant?
An exposure does not mean you have an infection. Tell your prenatal care team what you ate. CDC's symptom table lists smoked fish among common sources of Listeria and says pregnant women should call the doctor right away if they have a fever and feel more tired and achy than usual.
Is hot-smoked salmon different from cold-smoked?
CDC and FDA do not sort smoked fish by smoking method. Their checks are whether it is refrigerated or shelf-stable, and whether it is cooked in a dish. FDA lists "kippered" and "smoked" among the labels used on refrigerated smoked seafood.
Is canned salmon OK?
Yes. CDC lists canned fish and seafood as a safer choice.
